Preparation of 1-p-Halophenyl and 1-p-Biphenylyl Substituted Monocarbadodecaborate Anions [closo-1-Ar−CB11H11]- by Insertion of Arylhalocarbenes into [nido-B11H14]

In the presence of a strong base, benzal chloride (C6H5CHCl2) and its p-substituted derivatives react with [nido-B11H14]- to yield [closo-1-p-X−C6H4−CB11H11]- (X = H, F, Cl, Br, I, Ph), presumably by insertion of an arylhalocarbene and oxidation. On a 1-g scale, the yields are 30−40%, except in the...

Description
Summary:In the presence of a strong base, benzal chloride (C6H5CHCl2) and its p-substituted derivatives react with [nido-B11H14]- to yield [closo-1-p-X−C6H4−CB11H11]- (X = H, F, Cl, Br, I, Ph), presumably by insertion of an arylhalocarbene and oxidation. On a 1-g scale, the yields are 30−40%, except in the case of p-iodobenzal chloride, which yields only 12% of the insertion product.
